SQL Server 2008 GEOGRAPHY STDistance() value

Question

I am using geography.STDistance() to return the distance between two single point locations. I\'m curious as to which measurement is used for the return value? Is it in KM\'

Answer 1

I think the return measurement depends upon the Spatial Reference Identifiers (SRIDs) of your geography data type. The default is 4326 which is in meters. There' a table in the DB you can check Select * from sys.spatial_reference_systems
